  The SAP error message R8305 "No structure of the DataSource & was found for hier. in source system" typically occurs when there is an issue with the DataSource configuration in the SAP system, particularly when dealing with hierarchical data sources. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Missing DataSource Structure: The error indicates that the system cannot find the structure definition for the specified DataSource in the source system. This can happen if the DataSource has not been properly activated or if it has been deleted or not created in the source system.
  
  
  Incorrect DataSource Configuration: The DataSource may not be correctly configured to handle hierarchical data, or it may not be set up to extract the required fields.
  
  
  Transport Issues: If the DataSource was transported from one system to another, there may have been issues during the transport process that led to missing components.
  
  
  Version Mismatch: There may be a version mismatch between the source system and the target system, leading to incompatibility in the DataSource structure.
  
  
  Solution:
  
  
  Check DataSource Activation: Go to the source system and check if the DataSource is activated. You can do this using transaction code RSA1 (Data Warehousing Workbench) and navigating to the DataSource in question.
  
  
  Recreate or Adjust DataSource: If the DataSource is missing or incorrectly configured, you may need to recreate it or adjust its settings. Ensure that it is set up to handle hierarchical data correctly.
  
  
  Transport Request: If the DataSource was transported, check the transport request for any errors. You may need to re-transport the DataSource or manually create it in the target system.
  
  
  Check for Updates: Ensure that both the source and target systems are updated to the same version of SAP, as discrepancies can lead to such errors.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific DataSource to ensure that all necessary configurations are in place.
  
  
  Use Transaction RSA3: You can use transaction RSA3 to test the DataSource extraction. This can help identify if the DataSource is functioning correctly.
